I have found that I am unable to edit posts that I make to ani.social using the default web interface lemmy-ui. I have tried in both firefox and chrome to no avail. I can reach the edit screen and hit the save button, but then the post just reverts back to how it was prior to my trying to edit it.

To circumvent this, I have found that editing using Jerboa on mobile works. I have not tried any other mobile apps. Also, editing comments works just fine even in the web-ui.
